This 3D-printed main mast is intended to help convert any 1/200 scale Iowa class battleship model kit to the 1950s through early 1980s appearance of USS New Jersey BB-62 or USS Missouri BB-63, and early 1950s appearance of USS Wisconsin BB-64. USS New Jersey BB-62 had this configuration through at least 1982. USS Missouri BB-63 had this configuration as late as 1984. Photos confirm USS Wisconsin BB-64 had this configuration at least circa 1953-1954.

Advice to correct warped parts: this design includes very long, thin legs that may warp during shipping. Warped parts are caused by the presence of uncured microscopic bits of resin within the parts which is a normal characteristic of 3D printing.
To correct the warp, fix the warped part(s) of the mast to a flat surface with clear plastic or clear tape being careful to position the bent legs in the desired, straight position. Then expose the mast to direct sunlight or a UV lamp for a few hours in order to fully harden the resin. When released from the tape or clear plastic, the now fully hardened parts should retain their straight shape. Ultraviolet light hardens the resin, not heat.
3D-printed acrylic plastic is brittle and breaks easily. Care is recommended during handling and assembly.
Depending on which kit you have, some adjustment of this mast or your kit's parts may be necessary for best fit.
This 3D design is based on 2D plans drawn by Mr. Henry Strub using the latest National Archives research conducted by him as well as exhaustive research conducted by Mr. Rick E. Davis.
